Analysing sound

• Non-diegetic sound
• At 2 seconds.
• cheerful/mundane music which is juxtaposed with what he is saying (killing his brother) "If I was thinking straight, I would've planned to kill him in a sensible way"
• Music continues over sound of explosion which contrasts 
• Upbeat, positive music 
• 0:44 sound bridge from one scene to another into diegetic at 0:48 (song continues to play from the radio inside the house). 
• 2:16 goes back to a soundtrack and non-diegetic

• Voice over - 4 seconds. Gruesome topic which contrasts with the music. Monotone, casual voice. 
• Voice over starts again at 2:16 (non-diegetic)

• Sound motif  2:48 sounds of the cars/bus/girls laughing (diegetic) 
• 2:53 Sound of the teacher
